ABSTRACT:
In a stator of a rotary electric machine that includes a stator winding and a stator core having a plurality of slots, the stator winding is constituted of a plurality of series-connected regular U-shaped segments each of which has a pair of in-slot portions and a plurality of U-shaped irregular segments each of which has a pair of in-slot portions disposed in a pair of slots that is suitable to connect the regular segments to form the stator winding and a continuous crossover portion crossing over some of the regular segments. The irregular U-shaped segments extend to be in contact with the turn portions of the regular segments. Therefore, the regular segments are connected by the irregular segments that have least electric resistance.
